To all whom it may concern.'

Be it known that we, RALPH K. SNOW and ALBA B. Pnnnrmyboth citizens of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Moving-Picture Apparatus, of which the following is a speci-fica@ tion.

This invention relates to a moving picture apparatus, and pertains especially to an apparatus for producingl animated pictures-by the use of opaque sheets upon which the pictures are printed." l

It is anobject -of this invention to'provide an apparatus which may be used either for Vobserving pictures through an eye-piece by the aid of daylight, or for projecting the pictures. :j

It is another object-to provide an apparatus suitable for using pictures printed on opaque sheets. The sheets may be printed and suitable for distribution with newspapers as advertising sheets or sold separately. The form andy size of the sheets are immaterial to our invention; y

It isa further 'object of this invention .to provide a mandrelfor carrying the pictures which is so arranged as to properly display pictures in anup-rightl position, the pictures being printed on the sheet at an angle to the edges.

We accomplish these objects bymeans of the embodiment ofour invention-illustrated in the :accompanying drawing, in which:

Figure 1 isa perspective view of our moving picture apparatus, a portion thereof beingr broken away to show the interior.

Fig. 2 is a vertical section through the mechanism compartment.

Fig. 3 is one-form of sheet suitable' for use with the apparatus, and

Fig. i is another form of sheet suitable for use with Athe apparatus.

A casing 5 `isprovided which has partition walls 6 and V'Z' dividing 'the casing into three compartments.

The middle compartment houses themechanism for moving the pictures. The compartment at one end is a projecting compartment, and the compartment at the other end is a Vviewing compartment. The wall Z is provided with an opening- 8 for displaying a single picture at a time and wall' is provided with an opening 9 for simultaneously displaying a single picture at ajtime.

. Disposed: the mechanism compartment isa threaded shaft 10. .Shaft 10 is canted with respect to the compartment and is secured to' the walls of the casing, being held against rotation. Mounted upon shaft 10 is a mandrel 11. Mandrel 11 is of such diameter that it is substantially tangent to the walls-G and 7 at the openings S and 9. Upon rotation of lthe mandrel .the latter is moved 'longitudinally of the shaft 10 by reason of the threaded engagement therewith. Freelv mounted upon' the shaft 10 foi` rotation is a friction disk 12. 'Extending from the friction disk and secured thereto are bars 13 and 14. Bars 13 and 14; .pass through openings .in the mandrel so thatthe mandrel may slide upon the bars, but will be' compelled vto rotate with the bars and the disk 12.

Engaged' with the friction disk 12 is a friction wheel '15. Friction wheel 15 is mounted for rotation upon a tubular shaft 16 and isjour-naled in abearing 1f?. Splined .to shaft 16 is ,a clutch 18- arranged to clutch the friction wheel/15 -to the shaft.

Extend ing through stubul-arV shaft 16 and mounted for rotation ,therein is a driving 4shaft 19.

Secured to driving shaft 4 19 is a Geneva stop motion 20 which rotates shaft 1G. Upon the other end of shaft 19 yis mountedY a sprocket wheel' 20-which.is' free to rotate upon the Splined .to shaft 19 is a clutch .21 for shaft. engaging sprocket wheel 2O with shaft 19. Adjacent the upper wall :of the casing is a line shaft 22 provided with a sprocket wheel 23 alined with sprocket wheel 20. A sprocket chain 24C` is passed over sprocket wheels 20 and 23. Fixed to line shaft 22 is a frictionpinion 25 which is engaged with the friction disk 12. -A handle 26 is provided Von the shaft 119 for manual rotation thereof.

Pivotally secured to brackets on the casing are shifter rods 27 and 28. Shifter rod 27 is secured to clutch 21, and shifter rod 28 to clutch 18. Securing the ends of the shifter rods to each other, is a bar 29. Clutches 18 and 21 are so spaced by the har `29 that when one clutch is in engagement with its corresponding wheel, the other is disengaged from its corresponding wheel. Fingers 30 and 31 are formed on'the bar 29 and extend into the lon tudinal path of the mandrel ll so that w en the mandrel reaches the end of its longitudinal travel it will engage a finger and move the clutches to throw the wheel which is rotating the mandrel out of operation and engage the other wheel with the shaft, thereby returning the mandrel.

Shaft 10 is canted in order to provide for the use of sheets of pictures which may be conveniently printed. The sheets of pietures when disposed upon the mandrel to embrace the same will form a series of pictures in helical form. If a strip of a moving picture film is cut into lengths to accommodate the same to the length of a sheet and the same printed upon the sheet with one end of a strip at the bottom of the sheet and the contiguous end of the next strip at the top, the sheet when formed into a cylinder would form a continuous helix of pictures. The pictures if printed and cut in this way would not be displayed upright through the openings 8 and 9 if the shaft 10 was horizontal. For this reason we have canted the shaft to brace the pictures in an upright position. The strips of pictures may be printed on a rectangular sheet or they may be printed upon a sheet of the form shown in Fig. 4. The angle with respect to the horizontal in which the shaft is disposed will vary with the size of the sheet and the particular form of sheet.

Pictures are progressively displayed before openings 8 and 9. Light is admitted through the top of the viewing compartment in any suitable manner illuminating the pictures so that they may be viewed through the eye-piece. In the projecting compartment there is means for projecting light upon the picture from which it is reflected through the projecting lens. This last mentioned means, not shown, may be of any construction, several of which are well known in the art,-reflecting mirrors and lights at the forward end of the compartment adjacent the projecting lens.

What we claim is:

l. In a moving picture apparatus, the combination of a casing; partition walls in said casing dividing the latter into a viewing compartment, a mechanism compartment, and a projecting compartment, said partition walls provided with openings for the display of pictures, and an opening in said viewing compartment to admit light; an eye opening in a wall of said viewing compartment for observing pictures; a mandrel in said mechanism compartment for carrying chronopictures, said mandrel disposed to display a picture before each of said openings; operating mechanism for moving said mandrel to successively and intermittently dispose pictures before said openings; a projecting-lens in the Wall of said projecting compartment; and means in said projecting compartment to project light upon a picture, and reflect the same through said projecting lens.
